AUTOIIEOBILE-RADIATOR.

Application filed May 12, 1917'.

To a/t whom it/mcy concern Be it known that I, SHERMAN A. Barns, a citizen of the United States, residing at Collins, in the county of Story and State of Iowa, have invented a new and useful Auto- 1nobileRadiator, of which the following is a specification.

The device forming the subject matter of this application is a radiator of that general type used on motor propelled vehicles, and one object of the invention is to provide novel means whereby a thorough cooling of the water in the radiator will be brought about, novel means being provided for securing a circulation of the water about the cooling flues.

With the above and other objects in view which will appear as the description procoeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of What is claimed, without departin from the spirit of the invention.

n the accompanying drawings Figure 1 shows in vertical transverse section, a radiator constructed in accordance with the present invention;

Fig. 2 is a cross section showing the means whereby the fines are mounted in the front and rear walls of the radiator.

The radiator forming the subject matter of this application includes a front 1, a back 2, an end wall 3, and an end wall 4. EX- tended through the front 1 and the back 2 are flues 5. lflach fine 5 has at its forward end a flange 6, and interposed between the fian e 6 and the front 1 is a packing washer 7. ll packing washer 8 is carried by the rear end of the flue 5 and cooperates with the rear wall 2 of the radiator. A metallic washer 9 may be placed against the packing washer 8, the washer 9 bemg adapted to receive one end of a compression spring 10. A nut 11 is threaded onto the rear end of the fine 5 and constitutes means for tightening up the spring 10. The construction, obvi- Specification of Letters latent.

ously, is such that the front 1 and the back 2 of the radiator may expand and contract with respect to the fines 5.

The iiues 5 are disposed in lines extended transversely of the radiator. Projecting from the end l are baiiie plates 12, and projecting from the end 3 are baffle plates 14;. The battle plates 12 are spaced as shown at 15 from the end 3, and the baffle plates 1% are spaced as shown at 16 from the end 4:, the baffle plates 12 and 14, therefore, projecting, alternately, from the ends 3 and 1. The bathe plates lie between the lines of fines The battle plates 12 and ll preferably extend between the front 1 and the baclr 2, and the front and the back have projections whereon the baffle plates are supported.

ln practical operation, air passes through the fines 5, and the water in the radiator is compelled, by the baffle plates 12 and 141, to travel in a zigzag line about the fines, as will be understood readily when Fi 1 of the drawings is examined. 7

The general construction of the radiator is such that the water will be cooled adequately and thoroughly, and, at the same time, owing to the structure shown in Fig. 2, the necessary expansion and contraction is ossible.

laving thus described the invention, what is claimed is A radiator for use in connection with the internal combustion engine of an automobile, comprising end walls, a back and a front, the back and the front having in wardly extended projections; lines of spaced air thimbles extended between the front and the back and communicating at their forward and rear ends directly with the atmosphere; and battles located between the lines of thimbles to form a sinuous water passage through the radiator, the baffles projecting, alternately, from the respective end walls, each baffle terminating in closely spaced relation to the end wall opposite to the end wall from which the baffle projects, to form openings the full width of the leaffles, the openings being bounded by the ends of the baffles, the end Walls, the front and the back, the Width of each baflle being equal to the length of those portions of the thimbles which lie between the front and the back, the baflles being supported on the projections, each baifle having a flange c06pemt ing with the front, aspring coijperating with the back, and a nut retaining the spring, the spring permitting expansion, but

serving to retain the bafiies on the projec 10 tions.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.
